2-12 Before Using the Unit PAS SERIES
Next, let's consider the case when the output terminal is grounded.
Fig.2-11 shows the case when the + (pos.) output terminal is con-
nected to the chassis terminal. In this case, the + (pos.) output termi-
nal is at ground potential. Therefore, the cable and load that are
connected to the output terminal (including the sensing terminal) only
require an insulation capacity that is greater than the maximum out-
put voltage of the unit with respect to the chassis.
The same holds true when the - (neg.) terminal is connected to the
chassis terminal. The cable and load require an insulation capacity
that is greater than the maximum output voltage of the unit.

For safety reasons, connect either output terminal to the chassis ter-
minal unless your application requires the output terminal to be float-
ing.

Since the + (pos.) output
terminal is at ground
potential, the section
indicated in gray must have
an insulation capacity that is
greater than the maximum
output voltage of the unit
with respect to the chassis.
